The Internet of Things is still too hard. Even some of its biggest backers say so.
For all the long-term optimism at the M2M Evolution conference this week in Las Vegas, many vendors and analysts are starkly realistic about how far the vaunted set of technologies for connected objects still has to go. IoT is already saving money for some enterprises and boosting revenue for others, but it hasn't hit the mainstream yet. That's partly because it's too complicated to deploy, some say.
For now, implementations, market growth and standards are mostly concentrated in specific sectors, according to several participants at the conference who would love to see IoT span the world.
Cisco Systems has estimated IoT will generate $14.4 trillion in economic value between last year and 2022. But Kevin Shatzkamer, a distinguished systems architect at Cisco, called IoT a misnomer, for now.
"I think we're pretty far from envisioning this as an Internet," Shatzkamer said. "Today, what we have is lots of sets of intranets." Within enterprises, it's mostly individual business units deploying IoT, in a pattern that echoes the adoption of cloud computing, he said.
In the past, most of the networked machines in factories, energy grids and other settings have been linked using custom-built, often local networks based on proprietary technologies. IoT links those connected machines to the Internet and lets organizations combine those data streams with others. It's also expected to foster an industry that's more like the Internet, with horizontal layers of technology and multivendor ecosystems of products.
The good news is that cities, utilities and companies are getting more familiar with IoT and looking to use it. The less good news is that they're talking about limited IoT rollouts for specific purposes.
"You can't sell a platform, because a platform doesn't solve a problem. A vertical solution solves a problem," Shatzkamer said. "We're stuck at this impasse of working toward the horizontal while building the vertical."
"We're no longer able to just go in and sort of bluff our way through a technology discussion of what's possible," said Rick Lisa, Intel's group sales director for Global M2M. "They want to know what you can do for me today that solves a problem."
One of the most cited examples of IoT's potential is the so-called connected city, where myriad sensors and cameras will track the movement of people and resources and generate data to make everything run more efficiently and openly. But now, the key is to get one municipal project up and running to prove it can be done, Lisa said.
The conference drew stories of many successful projects: A system for tracking construction gear has caught numerous workers on camera walking off with equipment and led to prosecutions. Sensors in taxis detect unsafe driving maneuvers and alert the driver with a tone and a seat vibration, then report it to the taxi company. Major League Baseball is collecting gigabytes of data about every moment in a game, providing more information for fans and teams.
